A person I like is about to leave. What ancient poem should I use to express my disappointment?

There are many ancient poems that express farewell feelings.

For example, Li Bai's gift to Wang Lun: Peach Blossom Pond is deeper than thousands of feet, not as good as Wang Lun's gift to me.

another poem by Li Bai: I miss my heart and the bright moon, and I will stay with you until the night is long.

Comfortable: Mochow has no bosom friend in the road ahead, and everyone in the world knows you.

Wang Bo's: and yet, while China holds our friendship, and heaven remains our neighbourhood.

another song: My mind is wandering with me, and my life is bitter. Whether to leave or stay, will be the other person in the dream.

Wang Wei's: I advise you to drink one more glass of wine, and there is no reason to go out to Yangguan in the west.
